Overview
DOHO DOHO (4) Standard light source Color Assessment Cabinet is a four-light source Color detection device equipped with D65 international standard artificial daylight, TL84 European/Japanese/Chinese store light source, F family hotel light and UV light source. The light box does not require preheating and has no stroboscopic. It is designed to provide users with a stable and reliable Color evaluation environment. Its design is compact and easy to use.
Features
1. Display the usage time and total time of each light source.
2. The light source is automatically switched, with the same color spectrum function.
3. No preheating required, no flashing, ensuring fast and reliable evaluation of Color.
4. Low energy consumption, no heat (no heat dissipation required), high luminous efficiency.
5. Small size, easy to use, low price.
Principle
The light box simulates lighting conditions in different environments through a variety of built-in Standard light sources. During testing, the sample to be tested and the standard sample are placed in the light box, and the performance of Color under different lighting is observed by switching or combining specific light sources (such as D65, TL84, F, UV), so as to accurately evaluate Color conformity, homochromatic heterochromic effect or fluorescence characteristics.
Applications
Spinning & weaving Printing and dyeing, printing Encasement, Coating paints, plastic electronics, home building materials, automotive interiors, cosmetics, food, medicine, laboratory Color testing and quality control
Steps
Place the light box smoothly and connect it to the corresponding power supply (220V/50Hz or 110V/60Hz).
2. Turn on the power switch and start the light box.
3. Select the single light source (e.g. D65) to be used through the control panel or activate the automatic switching function.
4. Place the sample to be tested side by side with the standard sample in the middle of the baseplate of the light box.
The observer observes and evaluates the color at a 45-degree angle (additional 45-degree standard stands need to be purchased) or in the vertical direction.
6. It can be switched to the UV light source to check the fluorescent whitening agent or fluorescent characteristics of the material.
7. After use, turn off the power switch.
Notice
* Make sure to use the Power supply voltage (220V/50Hz or 110V/60Hz) that matches the nameplate of the light box.
Avoid frequent switching of light sources to prolong lamp life.
* When observing the color, should avoid external rays of light interference, it is recommended to use in the dark room.
The inner wall of the light box should be kept clean to avoid stains affecting the uniformity of the light field.
Do not look directly at UV light sources to avoid damage to your eyes.
* The 45-degree standard stand requires additional accessories and is not a standard configuration.
The equipment is heavier (28Kg), so it is necessary to pay attention to safety when moving.
